NGC 6337

This object is a tiny planetary nebula located 5000 light years away in the southern constellation of Scorpius. The bright ring has an apparent diameter of 1 arc-minute and a true diameter of 1.3 light years. The magnitude 12.3 object is best seen in the full resolution view.

I really like this object for a number of reasons:

1. The unusual number and clarity of colorful stars which appear inside of the ring, including what appears to be a bluish central star.

2. The bright torus ring. We have an excellent view of this ring since our apparent view of this bipolar planetary nebula is nearly pole-on.

3. The extended eye-shaped lobe area, which reminds me of a smaller version of the Helix Nebula.

4. The numerous tiny red "spokes" and bright white regions within the nebula. The white regions are cometary knots, as seen in the Helix and Eskimo Nebulae.

5. The bright and colorful star field creates a great backdrop for the nebula.

Despite being such an outstanding object, this is the only the 4th Astrobin image of this object and the first taken from the northern hemisphere. This object was difficult for me to image because of its small size and its low (-38 degrees) southern declination.

Some call it the Cheerio Nebula. I eat Cheerios every morning, but I have a hard time visualizing this object as a Cheerio. To me, it looks more like a frosted doughnut with sprinkles.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
